The Feliway Friends Diffuser Set includes both the plug-in diffuser unit and a 48ml refill vial. Feliway Friends uses a different pheromone than Classic — it specifically targets tension and conflict between cats in multi-cat households.

The diffuser releases a synthetic copy of the cat appeasing pheromone (CAP), which mother cats produce to calm their kittens. In multi-cat homes, this pheromone helps reduce hissing, fighting, blocking, and chasing between cats. The set provides everything needed to start — simply plug in and allow 7 days for initial effect. Each refill covers approximately 70 square metres.

Multi-cat households face unique stress dynamics that the standard Feliway Classic doesn't specifically address. Feliway Friends was developed to target inter-cat conflict, making it the go-to for homes where cats aren't getting along.
